Specifications Of Standard Wiring Components - Rotex RRRQ011AAV1 Installationsanleitung

Use a power wire pipe for the power wiring.
Outside the unit, make sure the low voltage electric
wiring (i.e. for the remote control, between units, etc.)
and the high voltage electric wiring do not pass near
each other, keeping them at least 50 mm apart.
Proximity may
malfunctions, and breakage.
Be sure to connect the power wiring to the power
wiring terminal block and secure it as described under
"9.4. Precautions on wiring of power supply and
inter-unit wiring" on page 13.
Inter-unit wiring should be secured as described in
"9.4. Precautions on wiring of power supply and
inter-unit wiring" on page 13.
• Secure the wiring with clamps so that it does not touch
the piping.
• Make sure the wiring and the electric box lid do not
stick up above the structure, and close the cover
firmly.
9.5. Specifications of standard wiring components
A power circuit (see table below) must be provided for connection of
the unit. This circuit must be protected with the required safety
devices, i.e. a main switch, a slow blow fuse on each phase and an
earth leakage breaker.

Wire type
(a) Stated values are maximum values (see electrical data of combination with
indoor units for exact values).
(b) Only in protected pipes, use H07RN-F when protected pipes are not used.
NOTE Select the power supply cable in accordance with
relevant local and national regulations.
Wire size must comply with the applicable local
and national code.
Specifications for local wiring power cord and
branch wiring are in compliance with IEC60245.
The earth leakage circuit breaker must be a
high-speed type breaker of 300 mA (<0.1 s).
In connecting the power cable to the power terminal block,
securely clamp the cable as shown in figure 8.
After finishing the electric work, confirm that each electric
part and terminal inside the electric parts box is connected
securely.
For V1 models only : Equipment complying with EN/IEC 61000-3-12
(1) European/International Technical Standard setting the limits for harmonic
currents produced by equipment connected to public low-voltage systems
with input current >16 A and ≤75 A per phase.

Precautions when laying power wiring
Use round pressure terminals for connections to the power
terminal block.
When none are available, follow the instructions below.
Do not connect wiring of different thicknesses to the
power terminal block. (Slack in the power wiring may
cause abnormal heat.)
When connecting wiring which is the same thickness,
do as shown in the figure below.

For wiring, use the designated power wire and
connect firmly, then secure to prevent outside
pressure being exerted on the terminal board.
Use an appropriate screwdriver for tightening the
terminal screws. A screwdriver with a small head will
strip the head and make proper tightening impossible.
Over-tightening the terminal screws may break them.
See the table below for tightening torque for the
terminal screws.

Field line connection: Control wiring
Be sure to follow the limits below. If the unit-to-unit cables
are beyond these limits, it may result in malfunction of
transmission.
Maximum wiring length: 300 m
Total wiring length: 600 m
The wiring from the indoor unit must be connected to the F1/F2
(In-Out) terminals on the PC board in the outdoor unit.
After installing the interconnecting wires inside the unit, wrap
them along with the on-site refrigerant pipes using finishing
tape, as shown in the figure.
